Troubleshooting Installation

flockrsd fails to start

  • systemd PolicyKit / polkit failure

PolicyKit / polkit is the "sudo of systemd". If you have PolicyKit / polkit active on the install host, and you want to start flockrsd as an unprivileged user, you will need to add PolicyKit / polkit configuration for flockrsd. Alternatively you can just run service flockrsd start as root or under sudo.
